UMI Performance 1978-1988 GM G-Body Double Adjustable Upper & Lower Rear Control Arm Kit - Ultimate Arms 302717-B

Fits select 1978-1988 Buick Regal, Chevrolet Malibu, Chevrolet Monte Carlo, Oldsmobile Cutlass, and Pontiac Grand Prix/LeMans.

The UMI Performance 302717-B kit provides a complete rear suspension overhaul for the GM G-Body platform, designed to eliminate wheel hop and improve traction. This kit includes double-adjustable upper and lower control arms, allowing for precise on-car tuning of the pinion angle and rear axle centering without the need to remove the arms from the vehicle. By replacing factory stamped-steel components and soft rubber bushings with heavy-duty tubing and spherical rod ends, this system ensures zero-deflection and consistent suspension geometry during hard launches and aggressive cornering.

• On-Car Adjustability: Double-adjustable design allows for pinion angle and wheelbase corrections while the suspension is loaded.
• Zero Deflection: Equipped with high-quality spherical rod ends to maximize articulation and eliminate the bind common with polyurethane or rubber bushings.
• Complete Kit: Includes one set of Double Adjustable Lower Control Arms (Item #3027) and one set of "Ultimate Arms" Double Adjustable Upper Control Arms (Item #3017).
• Construction: Manufactured from heavy-duty steel with a durable black powder-coated finish for corrosion resistance.
• Manufacturer Part Number: 302717-B
